摘　　要：采用Matlab对开关电源的控制模式进行了仿真分析。采用离散分析方法,对于用解析方式无法求解的状态方程进行了离散处理,分析了开关电源系统的动态性能,包括负载突变、输入特性分析以及系统从初态到稳态的建立过程。阐明了仿真程序的编制方法及该仿真方式的特点。并充分利用Matlab强大的计算功能,运用矩阵运算编制程序,使程序流程更加简明。The control mode of switching mode power supply (SMPS) is simulated and analyzed using matlab in this paper. Discrete analysis is adopted, which can solve the equations that can not be solved by analytic method. Dynamic performance, input characteristics and the process from initial state to steady state of SMPS are also analyzed. Algorithm of simulation program and characteristics of this simulation mode are illustrated. Furthermore, the program is compendious using matrix and matlab, which has strong ability to calculate.
